Transport of particulate heavy metals towards the China Sea: a preliminary study and comparison

Polycyclic aromatic hydrocarbons (PAHs) in continental shelf sediment of China: Implications for anthropogenic influences on coastal marine environment

“…4) suggested that hydrodynamic transport was not the dominant input mechanism. In addition, a previous study also suggested that atmospheric input was more important than riverine input in transporting metals to the Yellow Sea (Zhang et al, 1992). Moreover, the compositional profile of sediment PAHs in Yellow Sea was dominated by high-molecular weight (5 þ 6-ring) PAHs (50e72% with a mean of 60%; Fig.…”

Use of lipid biomarkers for identification of regional sources and dechlorination characteristics of polychlorinated biphenyls in the East China Sea

“…2a and Table S4) suggested that the mud area is a significant sink of PCBs, such as several other contaminants of PAHs (Guo et al, 2006), heavy metals (Zhang et al, 1992), and SCCPs (Zeng et al, 2012). Southwest of Cheju Island is a modern depositional center of the ECS (DeMaster et al, 1985), and the sediments mainly originated from OHE in northern Jiangsu Province (Milliman et al, 1989).…”

“…The pollutants from East Asia can be transported to the northern Pacific Ocean by the East Asian monsoon (Wilkening et al, 2000). Hence, the northern ECS is located downwind of North China and the pathway for terrestrial pollutants to the northern Pacific, resulting in many pollutants entering the northern ECS through atmospheric deposition (Guo et al, 2003;Zhang et al, 1992). The lighter PCBs are more prone to accumulate in the atmosphere and be transported farther from the source compared with the heavy congeners.…”

Sources and preservation of sedimentary organic matter in the Southern Bohai Sea and the Yellow Sea: Evidence from lipid biomarkers

“…The carbon number maxima shifted from nC29 to nC31 in SYS reflecting the contribution of terrestrial n-alkanes derived from different sources. In addition, long-range atmospheric transport is an important input path for sediment in SYS, resulting in a potential contribution of TOM to OM pool (Zhang et al, 1992). Therefore, although the provenance of sediment in SYS was not yet clear, the terrestrial n-alkanes from the Yellow River discharge had a relatively small contribution in SYS.…”
